## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability world-bank-under-5-mortality-rate-by-country-cf16a153 -d '<json body>'
```

Example prompt: Can you pull up the latest under-5 child mortality rates per 1,000 live births for every country in the world from the World Bank dataset?

## When to prefer this

Use this endpoint when you need a comprehensive, ready-to-use global snapshot of under-5 child mortality rates across all countries and regions in a single call, without needing to specify any country code or filter. Ideal for global comparisons, data enrichment, and health analytics dashboards. Prefer this over building a direct World Bank API integration when you want a simple no-parameter JSON response.

## Known failure modes

- Network or upstream World Bank data unavailability returns a non-200 error
- Payment failure (x402 protocol) if USDC balance is insufficient — returns 402 status
- Data may lag behind the absolute latest World Bank release if the cache is not refreshed
